Good question-- kind of like the "paper expert" who used to hang out on Edmunds filter thread. Whenever I hear guys in large companies giving the straight scoop, I'm always worrying that they're being muzzled by the corporate big wigs (ala Bob). In reality knowledgable contributors like Johnny do infinite credit to the companies they represent. I'm sure most of us have a far higher opinion of Pennzoil (and Schaeffers for that matter) because of their inputs.
